Firefox 3.6x vs Firefox 9?

[Malware Removal Specialist]

Found some possible solutions/causes here.

Firefox very slow to load pages, how do I correct?

[Moderator]

It's not that it's slow to load pages - there is simply an occasional delay in mouse clicks being accepted and acted upon. Don't worry about it, just wondered if anyone else was having the same issue. However, there was one page in the link you posted that might be very interesting as a general reference for speeding up FF9 and I'm going to look through it - thanks

If wireless it could be the mouse...my new Logitech does this...energy - saving feature of course...

Same mouse I've been using for years. No, it's something to do with the new installation of FF9.

Hee hee...
I haven't changed as was strongly suggested....

Well, it appears my problem was being caused by Tab Mix Plus. As much as I like that add-on, once I disabled it the browser began working perfectly.

I have been having some odd little pauses; Having read your post I have disabled Tab Mix Plus too. One less add-on to eat memory and slow down Firefox start. [EDIT] I did find I had lost the "open new tab at home page" functionality which I had with Tab Mix Plus, so I re-installed the New Tab Homepage addon (I had it before but had removed it because Tab Mix Plus duplicated it)

This potentially involves multiple edits to FF about:config and unless you are sure you'll remember which ones you altered and what the previous setting was you may want to back up your existing ones first. They are stored in

%appdata%\mozilla\firefox\profiles\prefs.js

and you can just make a copy of that file before you start tinkering. If you do something that messes things up, just close Firefox and rename/restore the original file.

MozBack creates a complete copy of User accounts including themes extensions and the about:config file...

I applied all of those tweaks and Firefox seems to be running OK, it seems quite responsive and snappy, but then it was before. Certainly no "slower" than before. I have a Windows 7 64 bit, 4 GB RAM, an AMD 3 GHz quad core Phenom II cpu and a 20 Mbit (down) 768 Kbit (up) cable connection, and I hadn't really noticed very much sluggishness before to be quite honest. I have backed up the prefs.js so I can switch between them and see if I see any differences. I have 3 tabs open and FF has a 344,000 K Working Set showing in Process Explorer.

Instead of Tab Mix Plus I've installed Tab Utilities (https://addons.mozilla.org/en-US/firefox/addon/tab-utilities/ ). Not quite as full featured as TMP, but close.

Switch to chrome it is way better

Stop already...

Do you use a lot of add-ons in firefox? If not, I think you should switch to opera. The limited add-ons is the only reason why I don't use opera on my main comp, otherwise it is a very fast and stable browser. I have seen the difference myself and I can tell that the programmers put more care into it. I was recently working on an old system with a 1.4GHz CPU and firefox was doing a lot of 'clipping' on even very simple pages with only a few graphics (especially wordpress). I put opera on there and problem solved. No 'clipping' was visible when scrolling. I know I will get a lot of **** for recommending a different browser, but whatever opera deserves it.

is it good that firefox is attempting their chrome-like speedy firefox releases?
